Robert Zubrin is an American aerospace engineer, author, and advocate for human exploration of Mars. He and his colleague at Martin Marietta, David Baker, were the driving force behind Mars Direct, a proposal in a 1990 research paper intended to produce significant reductions in the cost and complexity of such a mission. The key idea was to use the Martian atmosphere to produce oxygen, water, and rocket propellant for the surface stay and return journey. A modified version of the plan was subsequently adopted by NASA as their "design reference mission". He questions the delay and cost-to-benefit ratio of first establishing a base or outpost on an asteroid or another Apollo program-like return to the Moon, as neither would be able to provide all of its own oxygen, water, or energy; these resources are producible on Mars, and he expects people would be there thereafter.

Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
Randii Ray Wessen is an American astronautics systems engineer specifically involved in planetary exploration, experimental economist, and writer. Dr. Wessen has been an employee of the California Institute of Technology's Jet Propulsion Laboratory since 1984. He is currently the A-Team Lead Study Architect for JPL's Innovation Foundry. On the side, Wessen works with Dr. David Porter of Chapman University in the field of Experimental Economics, where they are designing a system to help allocate resources for building instruments on robotic deep space planetary spacecraft. This proposed system will build on the success of the Cassini Resource Exchange and be applied to NASA's Outer Planet Flagship Missions.
Eugene F. Lally was American aerospace engineer. He worked in the early 1960s on U.S. interplanetary space programs. Beside his space programs he was also an inventor and developed non-space products with his own company Dynamic Development Co. which he founded in the early 1960s. He later became an active amateur photographer and lubrication product entrepreneur. Lally contributed articles for popular space, astrobiology, photography, travel, and archaeology magazines. He was also a speaker at local space exploration and extraterrestrial intelligence (UFO) society meetings where he gave first-hand accounts of the early U.S. space program, commentaries on current U.S. space exploration activities and the search for extraterrestrial intelligence.
A Mars aircraft is a vehicle capable of sustaining powered flight in the atmosphere of Mars. So far, the Mars helicopter Ingenuity is the only object to ever fly on Mars, completing 39 successful flights covering 7.90 km (4.91 mi) in 1 hour, 4 minutes and 20 seconds of flight time.
Adam Diedrich Steltzner is an American NASA engineer who works for the Jet Propulsion Laboratory (JPL). He worked on several flight projects including Galileo, Cassini, Mars Pathfinder, Mars Exploration Rovers (MER). He was the lead engineer of the Mars Science Laboratory's EDL phase, and helped design, build and test the sky crane landing system.
Robert J. "Bob" Parks was a US aerospace engineer and pioneer in the space program where he was intricately involved and/or directed for some of the most historic and important U.S. unmanned space missions. Over a 40-year tenure at the Jet Propulsion Laboratory (JPL/NASA), located in Pasadena, California, Parks’ impact was essential to helping the United States lead the world in space exploration. He served as Guidance Engineer for Explorer 1, the first successfully launched satellite by the United States. He directed the initial flyby missions to the Moon, the first soft landing on the moon, the world's first successful mission to another planet and initial missions to Mars, Saturn, Jupiter and Uranus. Parks concluded his career as Deputy Director of the JPL/NASA and retired in 1987. Some of the awards he received for his work include the NASA Exceptional Service Medal (1967), the Stuart Ballantine Medal (1967), the Goddard Astronautics Award (1980) and the Caltech Distinguished Alumni Award in 1982.
Robert Samuel Kraemer was an American aerospace engineer who served as Director of Planetary Programs at the National Aeronautics and Space Administration from 1971 to 1976.
Olivier L. de Weck is the Apollo Program Professor of Astronautics and Engineering Systems at the Massachusetts Institute of Technology (MIT).
